چکیده

Abstract This work reports on the electroanalytical performance of a glassy carbon electrode (GCE) modified with antimony and bismuth (Sb/Bi‐GCE) in detecting heavy metal ions using lead cadmium as model analytes. The Sb/Bi‐GCE surface was compared to (Bi‐GCE) well (Sb‐GCE). exhibited excellent figures merit Bi‐GCE Sb‐GCE surfaces. For example, limit detection for 0.01 ppb 0.1 1 Sb‐GCE, respectively.

Simultaneous Determination of Cadmium and Lead Using PEDOT/PSS Modified Glassy Carbon Electrode

In this work, we report the simultaneous determination of cadmium and lead using glassy carbon electrodes (GCE) modified by poly(3,4-ethylenedioxythiophene) (PEDOT) for linear sweep anodic stripping voltammetry (LSASV). The modification allows metal detection without involving oxygen removal, mechanical stirring and introduction of alloying additions such as Hg, Bi, Sb, etc. during the pre-conc...

Nile Blue- Chitosan Composite as a new Electrochemical Sensor for Uric Acid on Glassy Carbon Electrode

Nile blue-Chitosan NB-CH as a new type of organic days-organic composite was made using Nile blue and chitosan. The NB-CH composite was made using a 0.005 M solution of Nile blue NB and a 7 solution of chitosan. To do this, a mixture of Nile blue and Chitosan with the ratio of 2:1 was prepared. The electrocatalytic oxidation of uric acid UA has been studied on glassy carbon electrode by NB-CH u...
